Has anyone come across the problem where their point and shoot camera becomes a lot slower than when it was first bought? The Canon A540 that my friend bought last year was functioning well last year, now, after pressing the shutter to take a picture, it takes up to 3-5 seconds before the camera is ready for another shot. We have changed to new batteries, but no help. Also, this is the case even when the flash is not used. Any suggestions on how to fix this?

My Aladin dive computer has finally given in after 15 years and I need to buy a new one. While I appreciate the benefits of diving conservatively, which I practice, I have tried Suunto stinger, but find that the dive table it uses is too conservative. By the time I do a second dive in the morning, it goes into decompression mode within 15-20 mins. On my old Aladin, it is much easier to keep within the NDL. A friend of mine who is using one of the newer aladin wrist watch computer also seems to be quite conservative. Does anyone know which dive computer on the market uses the same dive table as the old Aladin (chunky rectangular shaped grey one which can either be worn on the wrist or put in a console).
